For Metalurgia:
The primary air is adjusted by the air inlet control positioned on the firedoor under the glass.
The primary air is adjusted by moving the regulator.
When the primary air regulator is positioned in:
End left position -close
End right position -open
close open
Fig.3. - The secondary air is adjusted by the factory and it cannot be re-adjusted.
The fuel is placed on the top grate and then it is fired. If there is not enough oxygen the door of
the ashtray can be barely opened (for Plamak, Plamak B). After the fuel is fired well the ashtray
door has to be closed. After that the intensity of the burning is regulated by the regulators for
primary and secondary air supply.
For constant burning you have to add wood or coals by spreading them on the whole grate.
Attention!
When the oven is used you need to add more fuel. The flue gas volume is bigger and the
temperature heating will be even and constant.
4.2.2. Upper ignition.
Regarding Plamak and Plamak B only.
The upper ignition is used when the cooker is used only
for heating. Before ignition the top grate is removed and the firedoors are closed. The fuel is added
from the top cover positioned on the top plate, and a vertical wood log is placed in the middle. It’s
recommended that the coals are placed till the level of the removed grate, which will allow opening
of the upper firedoor and ignition of the fuel from there. After the fuel is well ignited, ignition
adjusting is enabled as when lower ignition process.
4.3. Recommendations for ventilation.
Very important factor for proper burning of the cooker is to ensure additional air supply in the
room, which should be minimum 4m
3
/h for kW of the total heating power. If there are additional
heating appliances in the room it is necessary to provide additional 1.6m
3
/h for kW air supply at
every hour and at each kW form the total heating power.
A ventilator for suction of the air from the room (desiccators, tumble driers, etc.) working at
the same time with the cooker leads to change in the flue draught and consequently to bad burning
conditions of the cooker. In this case for the proper burning to be achieved it is necessary to let
additional air into the room.
4.4. Heating during the transitional period
For the good functioning of the cooker, it is necessary to achieve enough draught of the
chimney. This depends on both its height and the ambient temperature. At temperature exceeding
14
C disturbances in the combustion caused by insufficient draught might occur. In this case it is
necessary to load the cooker with less fuel and the regulators to be left open so that the fuel to be
burned faster (with flame) and thus reaching a stable flue draught in the chimney. In this case it is
necessary to clean the ashpan more often.
5. Cleaning.
The right exploitation of the cooker requires regular cleaning of the chimney, the fluepipes and
the cooker itself, from the soot and tar.
You can clean the ashtray only when the stove is cold.
Cleaning can be done when the top plates are removed and the surrounding steel plates
around the oven are cleaned. The soot is collected under it. The bottom of the oven is movable and
can be pulled out for complete cleaning. When the bottom plate is returned you have to ensure
that the sealing is right.
Proper maintaining of the cooker can guarantee the good look of the product for a long time.
